#### Automatically Adjust Probe Head Wrist

(This item pertains to the check boxes on the General tab of the Setup Options dialog box. You can open it through the F5 key or through the Edit | Preferences | Setup menu option.)

If you select the Automatically Adjust Probe Head Wrist check box, then during execution when the software reaches a TIP command, it will, based on the geometry, automatically select the tip for which the IJK of the tip shank most closely approximates the IJK on the TIP command. The IJK on the TIP command is relative to part coordinates so the tip actually selected can vary based on the part alignment.

WARNING: If you want PC-DMIS to recalculate the wrist angles in the face of a change in the workpiece alignment, you must ensure that the Automatically Adjust Probe Head Wrist check box is selected before you execute the measurement routine.
The TIP commands in the measurement routine will be updated with the new angles at each execution.

How it Works with Non-Mapped Wrists

For non-mapped wrists, PC-DMIS returns the closest theoretical position. If there is a calibrated tip that matches this theoretical position, PC-DMIS uses that calibrated tip. If PC-DMIS can find calibrated tips that fall within the angle tolerance defined in the Wrist warning delta box on the Part/Machine tab, it’ll use those tips over non-calibrated tips that have closer angle matches. (For more information about the tab, see "Setup Options: Part/Machine tab").

If PC-DMIS cannot find what it thinks is a theoretical match, it gives the error "Illegal TIP command or TIP not qualified".

If PC-DMIS found a good theoretical match but that tip doesn't exist or isn't yet calibrated, it will wait until the machine catches up to the TIP statement so no machine motion is in progress. The software then asks you if it should use the closest calibrated tip.

- If you select YES, PC-DMIS uses the calibrated tip.

- If you select NO, PC-DMIS adds a tip object to match the best theoretical fit and halts, but does not cancel, the execution. A message appears on the PC-DMIS status bar to press continue when you're done calibrating the new probe. At this point, you should access the Probe Utilities dialog box (Insert | Hardware Definition | Probe), perform any calibration work as needed, and then click Continue.

If you select the Automatically Adjust Probe Head Wrist check box and click the Mark Used button in the Probe Utilities dialog box, PC-DMIS may not select all the probe tips for calibration. For more information about the Mark Used button, see the "Mark Used" topic in the "Defining Hardware" chapter.

How it Works with Mapped Wrists

With an infinite wrist that is actually mapped (and therefore calibrated), PC-DMIS automatically returns the best matching tip position and proceeds using that position.

Other Notes

If you want PC-DMIS to continue to use the original tips during any execution of the measurement routine, then clear the Automatically Adjust Probe Head Wrist check box.
